Brief Summary: RATIONALE Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die Radiation therapy uses high-energy x-rays to damage tumor cells Combining chemotherapy with radiation therapy may kill more tumor cells
PURPOSE Phase II trial to study the effectiveness of irinotecan followed by radiation therapy and temozolomide in treating children who have newly diagnosed brain tumor
Detailed Description: OBJECTIVES
Evaluate the efficacy of adjuvant irinotecan in children with newly diagnosed high grade gliomas brain stem glioma or high risk grade II astrocytomas in terms of complete and partial response rate in patients with postoperative measurable disease and in terms of the rate of freedom from recurrence in patients with no postoperative measurable disease Determine the 3 year overall and progression free survival rates in this patient population when treated with adjuvant irinotecan followed by radiotherapy and temozolomide Assess the hematopoietic toxicity of temozolomide following local radiotherapy in this patient population
OUTLINE Patients receive postoperative irinotecan IV over 60 minutes daily for 5 days on weeks 1-2 Treatment repeats every 3 weeks for 2 courses Following completion of irinotecan and if appropriate patients may undergo a second surgical resection
Within 2 weeks following completion of chemotherapy or within 4 weeks of following a second resection patients receive image guided external beam radiotherapy 5 days per week for 6 weeks Patients with residual tumor less than 35 cm in maximal diameter may undergo boost radiosurgery
At 4 weeks following completion of radiotherapy patients receive oral temozolomide for 5 days Treatment repeats every 3 weeks for 6 courses
Patients are followed every 3 months for 2 years then every 4 months for 3 years
PROJECTED ACCRUAL A total of 50 patients will be accrued for this study within 5 years
